Traditional

Place milk and garlic into a saucepan and bring to a simmer for 30 minutes.  Drain and place the garlic into a small dish and coat with the oil.  Bake in the oven at 300 degrees for 20 minutes. 

Microwave Method

Place the unpeeled garlic in a small ovenproof container. Add olive oil to cover and sprinkle lightly with coarse salt. Cover with clear wrap and cook for 5 minutes at the high setting in a microwave. Squeeze the cloves out and leave whole. Spread on thinly sliced toast. Excellent as a starter with a good Chianti or Merlot.
